Thus, the spliced film shall be aligned to the extent that when one portion of the film is placed against a straigh
31、t edge, the other portion does not deviate by more than0,15mm (0,006in) per13cm (5in). 3 General requirements 3.1 Butt and overlap tape splices shall be made with an optically clear, transparent tape. 3.2 All splices shall be capable of withstanding a tension which is at least50% greater than the ga
32、te tension of the projector for that film width. 3.3 After splicing, the perforation holes shall be maintained clear at all splices. 3.4 If the film to be spliced contains a photographic sound track and the modulation level at the point of the splice results in any individual bias line having a widt
33、h of less than0,05mm, then the sound track should be blooped or opaqued to avoid an objectionable audio crash. 4 Overlap splices 4.1 General 4.1.1 The overlap provides the desirable increase in stiffness at the splice to prevent sharp angular bending when the film goes around a small radius, as in t
34、he free loops above and below the projection aperture. 4.1.2 When the overlap splice receives its mechanical strength from tape, it is usual not to scrape or otherwise remove the emulsion in the overlap area. 4.2 Recommendations for cemented overlap splices 4.2.1 The scraped area of one film end sho
35、uld be0,03mm to0,08mm (0,001in to 0,003in) narrower than the area covered by the overlapping film in order to prevent the appearance of a white line on the screen. 4.2.2 When splicing, the following recommendations should be observed: a) the cement should be applied to the full width of the splice;
36、b) no air bubbles should be in the splice; c) cement excess should be removed, including that from the perforation holes. 4.2.3 If the film being spliced contains a magnetic stripe, the stripe should be removed from the base of the film falling on top of the mating piece. 4.2.4 Bevelled splices are
37、recommended and scraping at an angle is preferred because it provides a stronger splice. When film with magnetic stripes is spliced, it is recommended that the overlap should be oriented so that the trailing film drops on to the scanning head rather than jolts up on to it. 4.2.5 An overlap cement sp
38、lice may be reinforced with splicing tape. 5 Butt tape splices 5.1 Butt splices shall be made centrally on the frame line. 5.2 The clearance between the butted edges of the print at the splices shall not exceed0,08mm (0,003in). Figure 5 For all film widths Dimension mm in E max. 0,33 0,013 G max. a
39、0,05 0,002 a A difference in the lateral shrinkages of the two strips can make it impossible to maintain the tolerance. Shoulders formed by such misalignment should be bevelled.ISO6038:1993(E) BSI 11-1999 5 5.3 The dimensions of the tape applied to secure a butt splice shall not interfere with the f
40、ilm dimensions as specified in the International Standard for the particular film type. 5.4 The tape shall be wide enough to cover an area of at least half a frame on each side of the splice. It is preferred that the tape begins and ends on a frame line so that the splice will be less visible. 5.5 T
41、he tape shall adhere uniformly to the film without corrugations or entrapped air bubbles. 5.6 For films with photographic sound records, the width of the tape used shall cover the full width of the film on both sides. For films with magnetic sound records, tape used on that side which does not carry
42、 the magnetic record and balancing stripes shall cover the full width of the film. Tape used on the side carrying the magnetic record shall not be placed in an area contacted by the magnetic heads. 5.7 Butt splices shall not be made with tape on one side only since such films are not functional in p
43、rojection. 5.8 Butt splices shall not be made with tape wrapped around the film since this interferes with guiding.ISO6038:1993(E) 6 BSI 11-1999 Annex A (informative) Bibliography 1 ISO 69:1990, Cinematography 16 mm motion-picture and magnetic film Cutting and perforating dimensions. 2 ISO 466:1976,
